The most common mistake is the reversal of the negative. There was an American Rifleman magazine cover that did that. The designers admitted they did it because the title of the magazine would have covered part of the painting. Oops.

Movie posters are notorious for that. A "Beverly Hills Cop" poster was reversed.

I don't possibly see how a reversed negative can make the rounds point to the wrong end of the magazine.

Yes, in a reversed negative the entire magazine would orient in a different direction, but the relationship to which way the rounds were loaded to the magazine would remain the same.

Or am I just seeing things?

Reversal of the negative would have reversed everything, it would not look the same as bullets loaded backward in the magazine.
